Washed Coal
Beneficiated non-coking coal — G5 to G8 — with ash brought down for boilers that cannot take raw power-grade coal.
GradesG5 – G8
GCV kcal/kg4901 – 6100
Ash %16 – 28
Moisture %6 – 11
Washing takes a raw non-coking feed and reduces ash, so the same coalfield can supply a tighter specification. Washed G5 to G8 is the practical choice where a boiler, kiln or process limit is written on ash rather than on GCV alone. Yield, size and the exact ash band are confirmed against the washery dispatch, not assumed from the raw-coal grade.

GCV bands are Coal India's non-coking grade definitions, in kcal/kg. Moisture, ash, volatile matter, fixed carbon and sulphur are typical ranges for coal offered from this field, not a guaranteed loading analysis. The rake's sampling report confirms the consignment. Sizes are subject to availability.
